4.2 UDI.onParameterChange()

UDI.onParameterChange() is called whenever there is a change to the user-defined settings for your UDI. The function receives a data parameter which contains the new settings, as a parameters object. It also receives the same context information which is passed to UDI.onInit(), in data.context.

For example:

settingsFields: [
	// Number of bars for the average 
	{id: "period", caption: "Period", type: "int", defaultValue: 14, min: 2}

UDI.onParameterChange = function(data)

	// Get the latest user-selected value of the "period" parameter
	var period = data.parameters["period"];
